ID: CC17215
A massive, solid matrix of reddish dark chocolate brown ironstone displays a large triangular, shallow vug measuring 7.5 x 6.0 x 4.8 cm along each edge, on its top surface.  This shallow depression is completely lined with intergrown curved blades of off-creamy-white Siderite crystals, some tinted golden yellow.  To one side sits a single black Sphalerite crystal measuring approximately 8 x 6 x 5 mm on which sit hair-like acicular crystals of golden Millerite, with some coated with a light lime green mineral, possibly Jamborite, but this would require analysis.  A blocky 12 x 12 x 5 mm colourless to milky Quartz crystal also sits in the vug.
